The invention relates to a multi-modal missing tooth positioning method based on a random forest. The method comprises the following steps: S1, acquiring oral cavity CBCT image data; s2, obtaining a tooth number set and a missing tooth number set of the actual dentition; s3, determining an adjacent tooth of one missing tooth in the missing tooth number set through a preset first mode and a preset second mode, if the adjacent tooth meets a prediction condition, executing S4, otherwise, returning to S3 until all elements in the missing tooth number set are traversed; s4, calculating actual centroid coordinates of adjacent teeth; s5, obtaining a missing tooth centroid prediction model; s6, obtaining an actual centroid coordinate of the missing tooth; and S7, traversing all elements in the missing tooth number set. Compared with the prior art, the method has the advantages of coping with complex challenges caused by deletion of multiple teeth and the like.

The invention discloses an electric bucket tooth missing detection method, a memory and a processor, and the electric bucket tooth missing detection method based on an infrared visual translation invariant feature comprises the steps: obtaining central position coordinates of bucket teeth in two continuous frames of infrared images by using a neural network model according to a spatial structure relationship between a stability feature region and a bucket tooth region; gray level distribution of bucket tooth areas in two continuous frames of infrared images is obtained; if the gray levels of the bucket tooth areas in the two continuous frames of infrared images change, it is judged that the bucket teeth of the electric bucket are missing. Therefore, the center positions of the bucket teeth in the two continuous frames of infrared images are obtained, then the gray distribution of the bucket tooth area is obtained according to the center positions of the bucket teeth, and the gray distribution of the bucket tooth area in the two continuous frames of infrared images is compared, so that whether the bucket teeth of the electric bucket are missing or not is judged, detection on whether the bucket teeth are missing or not is more accurate and convenient, and the detection efficiency is improved. The reliability and the stability of the electric bucket tooth missing detection method based on the infrared visual translation invariant feature can be improved.

This utility model relates to the field of dental technology. An occlusal reconstruction brace with a pressure post and spring retainer includes a first brace and a second brace that cooperate with each other. The first brace has a pressure post protruding towards the second brace, and the second brace has a clearance hole for the pressure post, which is used to allow elongated teeth to protrude. A spring retainer is symmetrically mounted on the first brace adjacent to the pressure post, allowing for the detachable installation of a spring. The spring retainer is used to detachably connect the spring, which is used to clamp between the tilted tooth and the spring retainer. The combination of the pressure post and spring retainer in this utility model uses the spring's elasticity to generate a straightening force on the tilted teeth on both sides of the missing tooth, and the pressure post applies longitudinal force to the elongated tooth at the site of the missing tooth, thus depressing the elongated tooth.

The application provides a method and device for assisting in positioning a tooth implant site based on a deep learning method, a computer readable storage medium, an electronic device and a surgical robot system. The method for assisting in positioning the tooth implant site comprises: performing dimension reduction processing on input image data; scaling the image after the dimension reduction processing to obtain a standardized two-dimensional image; using a preset tooth implant site positioning information extraction model to process the input standardized two-dimensional image file to obtain all tooth sites and tooth loss condition information of each tooth site. Thus, the tooth loss tooth site in all tooth sites can be identified, and all tooth sites with teeth, tooth sites with possible tooth loss or tooth sites with possible wisdom tooth growth are comprehensively predicted, thereby solving the problem that multiple tooth sites may be confused with each other in the traditional method and improving the accuracy. Because the input size can be arbitrarily adjusted, the demand for hardware devices is greatly reduced and the prediction speed is improved.
